我想知道如何按ID按php的形式排列我的选项？
<option value="9171">Name1</option>
<option value="5063">Name1</option>
<option value="6167">Name1</option>
<option value="5208">Name1</option>
<option value="4917">Name1</option>
<option value="4938">Name1</option>
<option value="6193">Name1</option>
<option value="6192">Name1</option>
<option value="5342">Name1</option>
<option value="6157">Name1</option>
<option value="5228">Name1</option>
<option value="2126">Name1</option>
<option value="1668">Name1</option>
<option value="6186">Name1</option>
<option value="5343">Name1</option>
<option value="4915">Name1</option>
<option value="9217">Name1</option>
<option value="7160">Name1</option>
<option value="9025">Name1</option>
<option value="9066">Name1</option>
<option value="9092">Name1</option>
从PHP，我如何按照ID顺序排列？ID是选项的值。我正在从media1.clubpenguin.com/play/en/web_service/game_configs/paper_items.json获取IDS
EDIT：如果你真的必须对<option/>列表进行排序，你可以这样做：
$options = <<<EOD
<option value="4917">Name1</option>
<option value="4938">Name1</option>
<option value="6193">Name1</option>
<option value="22">Name1</option>
<option value="5342">Name1</option>
<option value="6157">Name1</option>
<option value="7160">Name1</option>
<option value="9025">Name1</option>
<option value="9066">Name1</option>
<option value="1">Name1</option>
EOD;
$optionsArray = explode("'n", $options);
natsort($optionsArray);
print_r($optionsArray);
结果：
Array
(
[9] => <option value="1">Name1</option>
[3] => <option value="22">Name1</option>
[0] => <option value="4917">Name1</option>
...
)
注意natsort，它可以确保1和22值正确排序。
编辑结束。
// $json = file_get_contents('http://media1.clubpenguin.com/play/en/web_service/game_configs/paper_items.json');
$json = file_get_contents('paper_items.json');
$items = json_decode($json);
// sort by paper_item_id by keying by it
foreach ($items as $item)
{
$ordered[$item->paper_item_id] = $item;
}
// output options sorted by paper_item_id
$options = '';
foreach ($ordered as $id => $item)
{
$options .= "<option value='"$id'">$item->label</option>'n";
}
print $options;
结果：
<option value="1">Blue</option>
<option value="2">Green</option>
<option value="3">Pink</option>
<option value="4">Black</option>
<option value="5">Red</option>
